A sattvic diet generally consists of:
fresh, organic fruit and vegetables.
whole grains and nuts.
dairy products such as milk and ghee. (no dairy right now)
beans and lentils.
mildly sweet foods (natural, unrefined sugars), honey, molasses.
spices such as cinnamon, basil, coriander, ginger and turmeric.
That's it. Every once in awhile we'll have a Reishi drink. Or, some 100% cacao bar or other treat (a couple days ago I ate some brazil nuts!).
So far this has led to losing 10 lbs (I intend to go until at least the 20th of December). I also noticed that after the first 3-5 days I wasn't feeling the dietary change too much and I wasn't feeling cravings for anything. I have felt mildly disoriented from time to time - but I'm probably just disoriented because I'm not putting food into my mouth at the rate I'm used to. I'm not eating out as much as I usually do - that's come way down.
Overall, it's been a very interesting experience and I'd recommend it to anyone.
